- Make sure the kernel is configured correctly for the proprietary nVidia driver
- genkernel --menuconfig all
- Confirm: Loadable module support -> [*] Enable loadable module support
- Confirm: Processor type and features -> [*] MTRR (Memory Type Range Register) support
- Update: Device Drivers -> Character devices -> <*> /dev/agpgart (AGP Support)
- Confirm: Device Drivers -> Graphics Support -> < > nVidia Framebuffer Support
- Confirm: Device Drivers -> Graphics Support -> < > nVidia Riva support
- Confirm: Device Drivers -> Graphics Support -> <*> VESA VGA graphics support
- Update: Device Drivers -> Graphics Support -> VESA driver type (vesafb-tng)
- Reboot
- Make sure the /usr/src/linux symlink is pointing to the correct sources: ls -l /usr/src/linux
- Install the drivers (nvidia-kernel & nvidia-glx). Since nvidia-glx depends on nvidia-kernel, installing nvidia-glx is sufficient: emerge nvidia-glx
NOTE: Every time you compile a new kernel or recompile the current one, you have to run "emerge nvidia-kernel" to reinstall the nvidia modules. nVidia-glx is unaffected by a kernel change and doesn't even need to be rebuilt when you recompile/upgrade X.
- Load the kernel module into memory
- modprobe nvidia
- FATAL: Error inserting nvidia (/lib/modules/2.6.16-gentoo-r13/video/nvidia.ko): Unknown symbol in module, or unknown parameter (see dmesg)
- dmesg
- nvidia: Unknown symbol remap_page_range
- nvidia: Unknown symbol pci_find_class
- Supposedly the "stable" nvidia drivers in portage are really old. It's better to use the "testing" drivers. See http://gentoo-wiki.com/HOWTO_Unmask_Nvidia_Drivers
- Unmask the driver packages
- edit /etc/portage/package.keywords
- media-video/nvidia-kernel
- media-video/nvidia-glx
- Emerge the new version and confirm: emerge -av nvidia-glx
- Unload the old kernel module: rmmod nvidia
- Load the new kernel module: modprobe nvidia
- Success! Reboot to be sure... :)
- Configure X
- edit /etc/X11/xorg.conf
- Change the Driver line in the Device section from "nv" to "nvidia"
- Change the Module section and make sure that glx gets loaded and dri does not
- Make sure that in the Screen section, the DefaultDepth directive is set to 24
- Run eselect so that X uses the nvidia glx libraries: eselect opengl set nvidia
- Add user to the video group so he has access to the nvidia device files: gpasswd -a video
- Test the card
- startx
- glxinfo | grep direct
- should say that direct rendering is activated
- test FPS: glxgears
- Enable nvidia support for apps
- edit /etc/make.conf and add "nvidia" to the USE flags
- rebuild the apps that benefit from the USE flag change: emerge -uD --newuse world
- Error: device conflicts. Ignore for now. Maybe I'll come back & rebuild apps later
- Install nvidia settings tool:
- emerge media-video/nvidia-settings
- 1 config file needs updating, so find it: find /etc -iname '._cfg*'
- /etc/modules.d/._cfg0000_nvidia
- diff /etc/modules.d/nvidia /etc/modules.d/._cfg0000_nvidia
- minor differences, so just replace the original config with the new: mv /etc/modules.d/._cfg0000_nvidia /etc/modules.d/nvidia
- Run nvidia-settings to configure graphics
- Resolution is way too small.
- edit /etc/X11/xorg.conf
- delete "1280x1024" mode from Screen/Display/Depth=24 section. New default becomes "1024x768".
- reboot. Only fixes resolution in X.
- edit /boot/grub/grub.conf, change video statement to use 1024x768
- reboot
- much better!
